Load testing is one of the most accurate ways to check the health of a lead-acid battery. It measures the battery's ability to deliver current under a load. This test can help determine if the battery is capable of supplying the required current for a particular application. To perform a load test, you will need a load tester.
Check for any unintentional battery grounds. Clean all battery surfaces of foreign material. Check the battery room/building for proper operating ventilation, HVAC and lighting. Ensure that there is unobstructed access and egress path around the battery. Check for proper operating safety equipment (i.e. eye wash, spill containment, etc.).
Inspect and verify the structural integrity of the battery rack or cabinet. Using a calibrated and properly rated meter, measure and record the DC float voltage and current at the battery terminals. Is multiple strings involved, record the float current for each string.
